- European oceans are subject to rapid development. New activities such as aquaculture and ocean energy have gained importance. This triggers interest in “multi-use platforms at sea” (MUPS), i.e., areas at sea in which different activities are combined. MUPS are complex features with regards to technology, governance, and financial, socioeconomic, and environmental aspects. To identify realistic and sustainable solutions and designs for MUPS, the MERMAID project applied a participatory design process (PDP) involving a range of stakeholders representing companies, authorities, researchers, and NGOs. This paper evaluates if and how the participatory design process contributed to the design of multi-use platforms. It is based on interviews with the managers of the case study sites and a questionnaire administered to all stakeholders participating in the PDP workshops. Analyzing the four case studies, we conclude that the participatory design process has had a valuable contribution to the development of the four different designs of MUPS, even though the preconditions for carrying out a participatory design process differed between sites. In all four cases, the process has been beneficial in generating new and shared knowledge. It brought new design issues to the table and increased knowledge and understanding among the different stakeholders.

Tidskriftsartikel (refereegranskat)abstract
- Atypical regulation of inflammation has been proposed in the etiology of autism spectrum disorder (ASD); however, measuring the temporal profile of fetal inflammation associated with future ASD diagnosis has not been possible. Here, we present a method to generate approximately daily profiles of prenatal and early childhood inflammation as measured by developmentally archived C-reactive protein (CRP) in incremental layers of deciduous tooth dentin. In our discovery population, a group of Swedish twins, we found heightened inflammation in the third trimester in children with future ASD diagnosis relative to controls (n = 66; 14 ASD cases; critical window: -90 to -50 days before birth). In our replication study, in the US, we observed a similar increase in CRP in ASD cases during the third trimester (n = 47; 23 ASD cases; -128 to -21 days before birth). Our results indicate that the third trimester is a critical period of atypical fetal inflammatory regulation in ASD.

Tidskriftsartikel (refereegranskat)abstract
- European seas are encountering an upsurge in competing marine activities and infrastructures. Traditional exploitation such as fisheries, tourism, transportation, and oil production are accompanied by new sustainable economic activities such as offshore windfarms, aquaculture, and tidal and wave energy. One proposed solution to overcome possible competing claims at sea lies in combining these economic activities as part of Multi-Use Platforms at Sea (MUPS). MUPS can be understood as areas at sea, designated for a combination of activities, either completely integrated in a platform or in shared marine space. MUPS can potentially benefit from each other in terms of infrastructure, maintenance, etc. Developing MUPS in the marine environment demands adequate governance. In this article, we investigate four European sites to find out how governance arrangements may facilitate or complicate MUPs. In particular, we apply a framework specifying policy, economic, social, technical, environmental, and legal (PESTEL) factors to explore governance arrangements in four case study sites in different sea basins around Europe ( the Mediterranean Sea, the Atlantic Ocean, the North Sea, and the Baltic Sea). The article concludes with policy recommendations on a governance regime for facilitating the development of MUPS in the future.

- A 600 MW offshore wind farm is under construction in the Netherlands Exclusive Economic Zone at a site called Gemini situated 55 km north of the Wadden Sea island of Schiermonnikoog and 85 km from the nearest Dutch port ofEemshaven. This chapter investigates the option of introducing a multi-use design for the Gemini site by adding mussel cultivation (48 kt wet weight per year) andseaweed cultivation (480 kt wet weight per year) to the wind farm. An institutional analysis indicates a political will in the Netherlands to support the development ofadding uses to offshore wind farms, but a number of implementation obstacles are also identified. Those obstacles include an absence of licences for multi-use production and legal restrictions against third-party access to wind farms. There istherefore a need for a regulatory framework for multi-use and trust-building amongactors involved in multi-use installations. A financial and economic assessment,and a cost-benefit analysis also taking into account monetized changes in CO2 emissions, indicate that adding mussel cultivation to the wind farm is likely to be both financially and socio-economically viable. Including a seaweed cultivation function is probably not financially and socio-economically viable under currenttechnical and economic conditions. Knowledge gaps and uncertainties in these assessments with respect to, for example, missing site-specific data and non-monetizedexternalities suggest further research, also including pilot cultivations of mussels and seaweed in planned single-use or multi-use installations.

Horizontal Carrier Coordination through Cooperative Governance Structures

Tidskriftsartikel (refereegranskat)abstract
- This paper examines how governance structures found in the trucking industry impact the coordination between a forwarder and its carriers, including three cases: no forwarder coordination (direct contracting with shippers), investor-owned coordination (price-only contract), and carrier-cooperative coordination (revenue-sharing contract). The carriers are engaged in a Cournot competition, where they decide upon service provision and truck investment. Economic theory predicts that integration of firms under oligopolistic competition always leads to a more efficient supply chain in the sense that prices decrease and quantities increase, which reduces total profits. This suggests that the benefit of avoiding double marginalization does not outweigh the benefit of upstream competition in the successive oligopoly case, whereas both integrated and independent firms coexist, the integrated chains do perform better. In this paper we examine the interaction between governance structures, a key decision when managing supply chains, including that found in the trucking industry, and shippers willingness to procure trucking services instead of producing them using a private fleet. We find that cooperative governance can contribute to improved service provision, reduced service price, improved consumer surplus, and improved profit for the carriers in equilibrium. We use parameter values based on the Swedish trucking industry and a larger grocery retailer acting as shipper to numerically illustrate the impact of different governance structures.

Risk, information and incentives in telecom supply chains
- 2004

Ingår i: International Journal of Production Economics. - 0925-5273. ; 90:1, s. 1-16

Tidskriftsartikel (refereegranskat)abstract
- Supply chain management involves the selection, coordination and motivation of independently operated suppliers. The central planner's perspective in operations management translates poorly to vertically separated chains, where suppliers recurrently seem to object to benevolent information sharing and centralized decision rights. Seen from the supplier's perspective, such resistance may very well be rational. A downstream assembly line disclosing reliable information on actual and forecasted sales puts itself at a disadvantage when bargaining on share of chain profits. In this paper, we use a minimal agency model to contrast known optimal mechanisms with the actual practice in the telecommunications industry. A three-stage supply chain under stochastic demand and varying coordination and information asymmetry is modeled. A two-period investment-production game addresses the information sharing and specific investment problem in the telecom industry. The observed price-quantity contracts under limited commitment are shown to be inadequate under realistic asymmetric information assumptions. More a result of gradually evolving changes in bargaining power than coordination efforts, the upstream urge to coordinate may further deteriorate performance in terms of our model.
